Hotspots
On arrival (25/3/24) the Dual-Hat board had the wrong firmware (MMDVM_HS_HAT
) and would not operate correctly as a duplex/two-timeslot hotspot.
Pi-Star has capability to upgrade attached MMDVM firmware, but attempts to load MMDVM_HS_Dual_Hat
repeatedly failed
The firmware upload function was locked but unlocking was a simple matter of solder-bridging the pads of “JP1” on the MMDVM board.
Pi-Star Firmware upgraded successfully to MMDVM_HS_Dual_Hat v1.6
and duplex/two timeslot functionality was successful
